Just finished winterizing my boat - my first year with twin Yamaha outboards after 15 years with an I/O. I’ve gotta say it’s much better working on these outboards!
I changed changed oil in both, lower unit gear oil in both, plugs, gas filter, oil filter, all the standard fare, and except for a sticky drain plug for the oil on one, it all went smoothly. However I have ne question: I noticed that 2 out of the 8 spark plugs were rusted slightly (see pic). I should point out that these engines had a full 200 hr period since the last maintenance - I bought it mid season last year and annual maintenance was apparently never done. The bottom was never re-painted and it showed by mid-late season. But is this (albeit mild) corrosion something to worry about?
When I finished, I sprayed the whole lower part of the engine with Fluid Film rust inhibitor after reassembly. Winterized domestic water, bait wells and head, disconnected batteries and back fed a little coolant into the raw water wash down pump. I will do water separating filters, prop seals, and water pumps in the spring. Anyway, all is good, I am glad to get a close look at everything (it’s all *much* cleaner than servicing my old engine in the bilge) just wondering about that sporadic corrosion. Thoughts?
Also, what's the consensus about the water separating filters... - now or spring? I had intended on spring but someone locally said now is better. I can still swap them out, but would not be able to run the engines afterwards....
Looks like surface corrosion from a salt air environment and an engine that's never been washed down and sprayed down with Boeshield.
Change the plugs and spray the block and such down with Boeshield.
Doesnt matter what season you change the fuel/water separators, just as long as they are changed at regular intervals and checked for fuel contamination. I change mine after each season when I do my fluids.
I do most of my work when its convenient for me. I tinker with the boat over the winter while it's in my driveway. Sometimes I'll do my oils early winter after I pull the boat or early Spring before launch, just depends what's on my to-do list.
Since I dont have to do water pumps and impellers this year, I'll likely do the oils in Feb/March timeframe, along with the water/fuel separators.
